It's a Rails application and it does reflect the structure. It's the edit action on a controller, likely the UsersController. It looks like they tried to implement a user management system using has_secure_password and didn't know enough to do it properly.
They therefore created a default resource structure (probably using the rails scaffold generator command) which includes the id in the URL on all member routes, including the route for the edit action.
